Requires spt-core **v0.39.1 or newer** and Oh My Pi **v16.3.15 or newer**. Update with `spt adapter update omp-spt`, then restart existing endpoints so they load the corrected extension.

### Fixed
- **Repeated messages from the same peer attach to the current turn after resume.** Envelope correlation now targets the newest matching sender stub instead of an orphan stub retained in older conversation history, preventing a reply from opening a bare `<msg>` turn while its full SPT event is injected into the past.
- **Detached broker-hosted sessions remain controllable.** The minimum spt-core version is now v0.39.1, whose published bind/listen sequence preserves broker hosting authority instead of rendering a live session as `ONLINE - HARNESS ONLY`.
